使用腾讯云人脸识别接口，基于优图祖母模型。
一、准备工作
人脸识别账号
申请腾讯云服务器账号，生成自己的秘钥。记录秘钥和秘钥ID。
创建人员库
记下人员库id
在配置文件application.yml中添加配置。
plateocr:
SecretId: 秘钥ID
SecretKey: 秘钥
serverIp: iai.tencentcloudapi.com
area: ap-guangzhou #人脸识别服务器所在区域，官方推荐就近
groupId: 1 #刚才创建的人脸库ID
used: true #表示人脸识别是否开启
passPercent: 80 #通过率，相似率到达多少算通过
nonceStr: 123456 #随机数二、录入人脸的类
需要用到的类：
1.Base64Util ：自己写的base64工具类，用于将base64解码写到本地磁盘。
package com.qcby.mycommunity_003.util;
import org.apache.commons.codec.binary.Base64;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
public class Base64Util {
/**
* 将二进制数据编码为BASE64字符串
*
* @param binaryData
* @return
*/
public static String encode(byte[] binaryData) {
try {
return new String(Base64.encodeBase64(binaryData), "UTF-8");
} catch (UnsupportedEncodingException e) {
return null;
}
}
/**
* 将BASE64字符串恢复为二进制数据
*
* @param base64String
* @return
*/
public static byte[] decode(String base64String) {
try {
return Base64.decodeBase64(base64String.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
return null;
}
}
/**
* 将文件转成base64 字符串
*
* path文件路径
* @return *
* @throws Exception
*/
public static String encodeBase64File(String path) throws Exception {
File file = new File(path);
FileInputStream inputFile = new FileInputStream(file);
byte[] buffer = new byte[(int) file.length()];
inputFile.read(buffer);
inputFile.close();
return encode(buffer);
}
//读取网络图片
public static String encodeBase64URLFile(String path) throws Exception {
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setRequestMethod("GET");
conn.setConnectTimeout(5*1000);
InputStream is = conn.getInputStream();
byte[] data = readInputStream(is);
is.close();
conn.disconnect();
return encode(data);
}
public static byte[] readInputStream(InputStream inStream) throws Exception{
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
//创建一个Buffer字符串
byte[] buffer = new byte[1024];
//每次读取的字符串长度，如果为-1，代表全部读取完毕
int len = 0;
//使用一个输入流从buffer里把数据读取出来
while( (len=inStream.read(buffer)) != -1 ){
//用输出流往buffer里写入数据，中间参数代表从哪个位置开始读，len代表读取的长度
outStream.write(buffer, 0, len);
}
//关闭输入流
inStream.close();
//把outStream里的数据写入内存
return outStream.toByteArray();
}
/**
* 将base64字符解码保存文件
*
* @param base64Code
* @param targetPath
* @throws Exception
*/
public static void decoderBase64File(String base64Code, String targetPath) throws Exception {
byte[] buffer = decode(base64Code);
FileOutputStream out = new FileOutputStream(targetPath);
out.write(buffer);
out.close();
}
/**
* 将base64字符保存文本文件
*
* @param base64Code
* @param targetPath
* @throws Exception
*/
public static void toFile(String base64Code, String targetPath) throws Exception {
byte[] buffer = base64Code.getBytes();
FileOutputStream out = new FileOutputStream(targetPath);
out.write(buffer);
out.close();
}
}
2.RootResp 类，封装腾讯人脸识别返回的信息。
import com.alibaba.fastjson.JSON;
public class RootResp {
//腾讯api返回的状态码，如果是0代表添加成功，否则会有异常码
private int ret = 0;
public int getRet() {
return this.ret;
}
public void setRet(int ret) {
this.ret = ret;
}
private String msg;
public String getMsg() {
return this.msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
private Object data;
public Object getData() {
return this.data;
}
public void setData(Object data) {
this.data = data;
}
@Override
public String toString() {
return JSON.toJSONString(this);
}
}
3.FaceApi ：调用api接口

4.ApiConfiguration ：封装配置信息（调用腾讯接口需要的部分参数）
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@ConfigurationProperties(value="plateocr")
@Component
@Data
@ApiModel(value = "ApiConfiguration",description = "人脸识别参数描述")
public class ApiConfiguration {
@ApiModelProperty("人脸识别secretId")
private String secretId;
@ApiModelProperty("人脸识别secretKey")
private String secretKey;
// 服务器ip
@ApiModelProperty("人脸识别服务器ip")
private String serverIp;
// 服务器区域
@ApiModelProperty("人脸识别服务器区域")
private String area;
// 默认分组
@ApiModelProperty("人脸识别默认分组")
private String groupId;
// 用户id前缀，这个属性在配置文件里面没有
@ApiModelProperty("人脸识别用户id前缀")
private String personIdPre;
// 随机数
@ApiModelProperty("人脸识别随机数")
private String nonceStr;
// 是否使用
@ApiModelProperty("人脸识别，是否启用人脸识别功能")
private boolean used = false;
// 识别准确率
@ApiModelProperty("人脸识别比对准确度，如符合80%就识别通过")
private float passPercent;
}
5.表现层代码
@PostMapping("/addPerson")
public Result addFace(@RequestBody AddFaceVo personFaceForm){
//1============严谨性判断
Person person = personService.getById(personFaceForm.getPersonId());
if(person==null){
return Result.error("居民不存在");
}
if(personFaceForm.getFileBase64()==null||personFaceForm.getFileBase64().equals("")){
return Result.error("请上传base64编码的文件");
}
//1.腾讯接口使用的是腾讯优图祖母模型，
if(apiConfiguration.isUsed()){
//**************方法一：调用腾讯api识别。
String faceId = newPerson(personFaceForm, person.getUserName());
String faceBase = personFaceForm.getFileBase64().substring(0, 60);
// ************方法二：自己模拟判断是不是人脸图片************：
// String faceId = RandomUtil.getBitRandom();
//如果不是头像(这一行如果不注释就报错)
// if(faceBase.equals("iVBORw0KGgoAAAANSUhEUgAAAoAAAAHgCAYAAAA10dzkAAAAAXNSR0IArs4c")) {
// return Result.error("人脸识别失败");
// }
//2.存到本地的文件夹内
// //存储头像
String filename = faceId + "." + personFaceForm.getExtName();
// String savePath = face + filename;
// try {
// Base64Util.decoderBase64File(personFaceForm.getFileBase64(), savePath);
// } catch (Exception e) {
// e.printStackTrace();
// }
//**********************这是方法一结束*****************：
//生成头像访问路径
String faceUrl = urlPrefix + "community/upload/face/" + filename;
person.setFaceUrl(faceUrl);
person.setState(2);
person.setFaceBase(faceBase);
//3.存到数据库中（包括base64编码存储）
//更新人脸识别状态及图片地址
this.personService.updateById(person);
return Result.ok();
}
return Result.error("未开启人脸识别");
}
/**
* 腾讯api接口相关
* @param vo
* @param personName
* @return
*/
private String newPerson(AddFaceVo vo,String personName) {
String faceId = null;
String faceBase64 = vo.getFileBase64();
String extname = vo.getExtName();
String personId = vo.getPersonId()+"";
String savePath = face;
if (faceBase64!=null && !faceBase64.equals("")) {
FaceApi faceApi = new FaceApi();
RootResp resp = faceApi.newperson(apiConfiguration, personId, personName, faceBase64);
if(resp.getRet()==0) {
JSONObject data = JSON.parseObject(resp.getData().toString());
faceId = data.getString("FaceId");
if(faceId!=null) {
String filename = faceId + "." + extname;
savePath += filename;
try {
//调用自定义工具类，将base64编码文件解码，并报存在指定路径
Base64Util.decoderBase64File(faceBase64, savePath);
} catch (Exception e) {
e.printStackTrace();
}
}
}
else {
return faceId;
}
}
return faceId;
}
6.接收前端传递参数的类
import lombok.Data;
@Data
public class AddFaceVo {
private Integer personId;
private String extName;
private String fileBase64;
}三、录入人脸的流程
1.调用腾讯api
调用api需要的参数有：
配置文件中配置的秘钥、秘钥id、服务器ip、区域、人脸库id、是否开启、精确度、随机数
人员id、人员姓名、图片的base64码
2.如果腾讯接口返回的状态码是0，就说明保存成功，将图片存到本地。
3.更新数据库，存base64编码。
四、人脸识别
1.表现层代码
//1判断是不是在人员库存在)
// （1）调用腾讯AI接口(
FaceApi faceApi = new FaceApi();
RootResp resp = faceApi.searchPersonsReturnsByGroup(apiConfiguration, inOutFaceForm.getFileBase64());
String msg = "";
// 封装人员信息的json对象
JSONObject personInfo = null;
// （2）根据状态码，如果是0就是在人员库
if(resp.getRet() == 0) {
JSONObject object = JSONObject.parseObject(resp.getData().toString());
JSONArray resultsReturnsByGroup = object.getJSONArray("ResultsReturnsByGroup");
JSONObject returnsByGroupJSONObject = resultsReturnsByGroup.getJSONObject(0);
JSONArray groupCandidates = returnsByGroupJSONObject.getJSONArray("GroupCandidates");
JSONObject groupCandidatesJSONObject = groupCandidates.getJSONObject(0);
JSONArray candidates = groupCandidatesJSONObject.getJSONArray("Candidates");
// （3）拿到全部人员库对象，匹配数据库人员信息
String personId ="";
String faceId = "";
String personName = "";
String faceUrl = "";
long pid = 0;
Person p = null, p1 = null;
for(int i = 0;i < candidates.size();i++) {
personInfo= candidates.getJSONObject(i);
personId = personInfo.getString("PersonId");
faceId = personInfo.getString("FaceId");
personName = personInfo.getString("PersonName");
personId = personId.substring(4);
pid = Integer.parseInt(personId);
p = personService.getById(pid);
if(p == null)
continue;
else
p1 = p;
faceUrl = p.getFaceUrl();
if(faceUrl == null || faceUrl.equals("")){
continue;
}
faceUrl = faceUrl.substring(faceUrl.lastIndexOf("/")+1,faceUrl.lastIndexOf("."));
if(faceId.equals(faceUrl)) {
break;
}
}
// (4)
if(p==null) {
return Result.ok().put("data","人员信息不存在");
}
if(inOutFaceForm.getCommunityId() != p.getCommunityId()) {
return Result.ok().put("data","对不起，你不是本小区居民，请与系统管理员联系。");
}
// (5)创建出入记录对象，封装
InOutRecord inoutrecord = new InOutRecord();
inoutrecord.setCommunityId(p.getCommunityId());
inoutrecord.setPersonId(p.getPersonId());
try {
//保存图片
String newFileName = UUID.randomUUID()+"." + inOutFaceForm.getExtName();
String fileName = face + newFileName;
Base64Util.decoderBase64File(inOutFaceForm.getFileBase64(),fileName);
String basePath = urlPrefix + "community/upload/face/" + newFileName;
//查找系统中是否有该人员的出入场信息
InOutRecord inoutrecord1 = this.inOutRecordMapper.getInOutRecord(inoutrecord);
// （6）根据出去等于null来查，如果查不到就新建一个对象，查到了就是出去小区
//进入小区
if(inoutrecord1 == null) {
inoutrecord.setInPic(basePath);
this.inOutRecordMapper.insert(inoutrecord);
return Result.ok().put("status", "success").put("data", "【"+p.getUserName() + "】进入小区");
//离开小区
} else {
inoutrecord1.setOutPic(basePath);
inoutrecord1.setOutTime(new Date());
this.inOutRecordMapper.updateById(inoutrecord1);
return Result.ok().put("status", "success").put("data", "【"+p.getUserName() + "】离开小区");
}
} catch (Exception e) {
e.printStackTrace();
}
}else{
msg = "人脸识别失败,错误码=" + resp.getRet() + "," + resp.getMsg();
}
return Result.ok().put("data",msg);五、人脸识别流程
1.调用腾讯接口进行比对
2.根据状态码，判断是不是存在相似度通过的人脸。如果存在就和根据查找到的人员id来查找数据库中对应的id的人员的姓名。如果姓名也和人员库返回的一致就通过。
3.如需做进出登记，就在进出登记数据表中存入信息。
如果本id下是有“出”是null的就表示改人员是出小区，否则就新建一条记录，表示进小区。
